Environment, ecosystem, biome?Environment: It isdefined as the sum of total of all the living and non-living things around usinfluencing one another.Ecosystem: A group oforganisms interacting among themselves and with environment for exchangingenergy and matter is known as ecosystem.Ecologicalsuccession?. The progressive replacement of one community byanother till the development of stable community in a particular area is calledas ecological succession.Speciesdiversity?Species diversity is the diversity between differentspecies. The sum of varieties of all the living organisms at the species levelis known as species diversity. Food chain and food web with suitableexamples.
.Food Chain : A food chain is a picture or modelthat shows the flow of energy from Autotrophs to a series of organisms in anenvironment. A food chain only follows just one path as animals find food.
eg: Ahawk eats a snake, which has eaten a frog, which has eaten a grasshopper, whichhas eaten grass.• Example: grass –àdeer-àlionFood web : A food webis several food chains connected together. A food web shows the many differentpaths plants and animals are connected.
eg: A hawk might also eat a mouse, asquirrel, afrog or some other animal. The snake may eatDisasterpreperdeness includes? Includes: – Written plan– Education/training– Practicing the plan– Evaluating the plan and modifying it.Which are the nodal agencies responsible fordisaster management?Floods : Ministry of Water Resources, CWC• Cyclones : Indian MeteorologicalDepartment• Earthquakes : Indian MeteorologicalDepartment• Epidemics : Ministry of Health andFamily Welfare• Avian Flu: Ministry of Health, Ministryof Environment, • Ministry of Agriculture and AnimalHusbandry• Chemical Disasters : Ministry ofEnvironment and Forests• Industrial Disasters : Ministry ofLabour • Rail Accidents : Ministry of Railways• Air Accidents : Ministry of CivilAviation• Fire : Ministry of Home Affairs• Nuclear Incidents : Department of AtomicEnergy• Mine Disasters : Department of Mines Instruments to measure earthquake?. Earthquake magnitudeor amount of energy released is determined by the use of a seismograph.• The scale was developed by aseismologist named Charles Richter (Richter Scale, Range 1-9). • Second type ofscale, the earthquake intensity scale measures the effects of anearthquake where it occurs.
Landslides? Landslides are defined as the mass movementof rock, debris or earth down a slope. They are influenced by geological, geo-morphological, climatic,environmental, hydrological and seismological conditions and by biologicalfactors..Give the types of tectonics movement?• . Type of movement along the plate’s boundaries:– a) pulling away from each other (DIVERGENT) Biological disaster?. It defines the devastating effects that may be caused by an enormous spreadof a certain kind of living organism- that may be the spread off disease, avirus, an epidemics, but also just a sudden growth of population of certainkind of plants and animals e.g.
Ebola , swine flu What are the types of cyclone?Polar cyclone,Polar low, Sub-tropical, TropicalEcology.? )”The study of relationships between livingorganisms and the environments in which they live is the science of Ecology.” Carryingcapacity?.

Natural resources are naturally occurringsubstances that are considered valuable in their relatively unmodified(natural) form. • Therefore, Natural resources are the materialsrequired for sustenance of our life Soilerosion?Soil erosion is defined as the movement of soilcomponents, especially surface layer and top soil from one place to another Geothermalenergy?The energy harnessed fromthe hot rocks present inside the earth is called geothermal energy.Oceanthermal energy?. The energy available due to the difference intemperature of water at the surface of the oceans and at the deeper levels iscalled Ocean Thermal Energy What is Biomass energy?Biomass is the organic matter generated by plants oranimals which include crop residues, cattle dung, manure, sewage, agriculturalwaste etc Renewable resources?sResources which can neverexhaust. Once exhausted, they can be replenished by recycling, replacement orreproduction.
E.G SOLAR ENERGY, WIND ENERGY, Geothermal energy• Renewableresources are those resources which can restock (renew) themselves if they arenot over-harvested but used sustainably. Nonrenewable resources?A non-renewable resource is a natural resource thatexists in a fixed amount that cannot be re-made, re-grown or regenerated orreplaced after use.
e.g coal ,fossil fuel Climatechange?Climate change refers to any significant change in the measures of climate lasting foran extended period of time. In other words, climate change includes majorchanges in temperature, precipitation, or wind patterns, among others, thatoccur over several decades or longer
